After running rev-list --boundary to retrieve the list of boundary
commits, "git bundle create" runs its own revision walk. If in this
stage git encounters an unfamiliar option, it writes a message with an
unbalanced quotation mark:
error: unrecognized argument: --foo'
Drop the stray quote to match the "unrecognized argument: %s" message
used elsewhere and save translators some work.
This is mostly a futureproofing measure: for now, the "rev-list
--boundary" command catches most strange arguments on its own and the
above message is not seen unless you try something esoteric like "git
bundle create test.bundle --header HEAD".

Test "pushing to local repo" in t5800-remote-helpers can hang
due to a race condition in git-remote-testgit. Fix it by
setting stdin to unbuffered.
On the writer side, "git push" invokes push_refs_with_export(),
which sends to stdout the command "export\n" and immediately
starts up "git fast-export". The latter writes its output stream
to the same stdout.
On the reader side, remote helper "git-remote-testgit" reads from
stdin to get its next command. It uses getc() to read characters
from libc up until \n. Libc has buffered a potentially much
larger chunk of stdin. When it sees the "export\n" command, it
forks "git fast-import" to read the stream.
If fast-export finishes before git fast-import starts, the
fast-export output can end up in libc's buffer in
git-remote-testgit, rather than in git fast-import. The latter
hangs indefinitely on a now-empty stdin.

Instead of waiting until we record the parents of resulting merge, reduce
redundant parents (including our HEAD) immediately after reading them.
The change to t7602 illustrates the essence of the effect of this change.
The octopus merge strategy used to be fed with redundant commits only to
discard them as "up-to-date", but we no longer feed such redundant commits
to it and the affected test degenerates to a regular two-head merge.

Various failure modes in the repository detection code path currently
quote the wrong directory in their error message. The working directory
is changed iteratively to the parent directory until a git repository is
found. If the working directory cannot be changed to the parent
directory for some reason, the detection gives up and prints an error
message. The error message should report the current working directory.
Instead of continually updating the 'cwd' variable, which is actually
used to remember the original working directory, the 'offset' variable
is used to keep track of the current working directory. At the point
where the affected error handling code is called, 'offset' already
points to the end of the parent of the working directory, rather than
the current working directory.
Fix this by explicitly using a variable 'offset_parent' and update
'offset' concurrently with the call to chdir.
In a similar fashion, the function get_device_or_die() would print the
original working directory in case of a failure, rather than the current
working directory. Fix this as well by making use of the 'offset'
variable.
Lastly, replace the phrase 'mount parent' with 'mount point'. The former
appears to be a typo.

Since 88a21979c (fetch/pull: recurse into submodules when necessary) all
fetched commits are examined if they contain submodule changes (unless
configuration or command line options inhibit that). If a newly recorded
submodule commit is not present in the submodule, a fetch is run inside
it to download that commit.
Checking new refs was done in an else branch where it wasn't executed for
tags. This normally isn't a problem because tags are only fetched with
the branches they live on, then checking the new commits in the fetched
branches for submodule commits will also process all tags. But when a
specific tag is fetched (or the refspec contains refs/tags/) commits only
reachable by tags won't be searched for submodule commits, which is a bug.
Fix that by moving the code outside the if/else construct to handle new
tags just like any other ref. The performance impact of adding tags that
most of the time lie on a branch which is checked anyway for new submodule
commit should be minimal, as since 6859de4 (fetch: avoid quadratic loop
checking for updated submodules) all ref-tips are collected first and then
fed to a single rev-list.

We give the username and password to curl by sticking them
in a buffer of the form "user:pass" and handing the result
to CURLOPT_USERPWD. Since curl 7.19.1, there is a split
mechanism, where you can specify each element individually.
This has the advantage that a username can contain a ":"
character. It also is less code for us, since we can hand
our strings over to curl directly. And since curl 7.17.0 and
higher promise to copy the strings for us, we we don't even
have to worry about memory ownership issues.
Unfortunately, we have to keep the ugly code for old curl
around, but as it is now nicely #if'd out, we can easily get
rid of it when we decide that 7.19.1 is "old enough".

When we have a credential to give to curl, we must copy it
into a "user:pass" buffer and then hand the buffer to curl.
Old versions of curl did not copy the buffer, and we were
expected to keep it valid. Newer versions of curl will copy
the buffer.
Our solution was to use a strbuf and detach it, giving
ownership of the resulting buffer to curl. However, this
meant that we were leaking the buffer on newer versions of
curl, since curl was just copying it and throwing away the
string we passed. Furthermore, when we replaced a
credential (e.g., because our original one was rejected), we
were also leaking on both old and new versions of curl.
This got even worse in the last patch, which started
replacing the credential (and thus leaking) on every http
request.
Instead, let's use a static buffer to make the ownership
more clear and less leaky. We already keep a static "struct
credential", so we are only handling a single credential at
a time, anyway.

This is main test case for the original problem that triggered this
patch series. We create a repo with 50k tags and then test whether
git-clone over the smart HTTP protocol succeeds.
Note that we construct the repo in a slightly different way than the
original script used to reproduce the problem. This is because the
original script just created 50k tags all pointing to the same commit,
so if there was a bug where remote-curl.c was not passing all the refs
to fetch-pack we wouldn't know. The clone would succeed even if only one
tag was passed, because all the other tags were pointing at the same SHA
and would be considered present.
Instead we create a repo with 50k independent (dangling) commits and
then tag each of those commits with a unique tag. This way if one of the
tags is not given to fetch-pack, later stages of the clone would
complain about it.
This allows us to test both that the command line overflow was fixed, as
well as that it was fixed in a way that doesn't leave out any of the
refs.

The syntax for the use of mark references in fast-import
demands either a SP (space) or LF (end-of-line) after
a mark reference. Fast-import does not complain when garbage
appears after a mark reference in some cases.
Factor out parsing of mark references and complain if
errant characters are found. Also be a little more careful
when parsing "inline" and SHA1s, complaining if extra
characters appear or if the form of the dataref is unrecognized.
Buggy input can cause fast-import to produce the wrong output,
silently, without error. This makes it difficult to track
down buggy generators of fast-import streams. An example is
seen in the last line of this commit command:
commit refs/heads/S2
committer Name <name@example.com> 1112912893 -0400
data <<COMMIT
commit message
COMMIT
from :1M 100644 :103 hello.c
It is missing a newline and should be:
[...]
from :1
M 100644 :103 hello.c
What fast-import does is to produce a commit with the same
contents for hello.c as in refs/heads/S2^. What the buggy
program was expecting was the contents of blob :103. While
the resulting commit graph looked correct, the contents in
some commits were wrong.

HTTP authentication is currently handled by get_refs and fetch_ref, but
not by fetch_object, fetch_pack or fetch_alternates. In the
single-threaded case, this is not an issue, since get_refs is always
called first. It recognigzes the 401 and prompts the user for
credentials, which will then be used subsequently.
If the curl multi interface is used, however, only the multi handle used
by get_refs will have credentials configured. Requests made by other
handles fail with an authentication error.

When git-rebase--interactive stops due to a conflict and the only change
to be committed is in a submodule, the test for whether there is
anything to be committed ignores the staged submodule change. This
leads rebase to skip creating the commit for the change.
While unstaged submodule changes should be ignored to avoid needing to
update submodules during a rebase, it is safe to remove the
--ignore-submodules option to diff-index because --cached ensures that
it is only checking the index. This was discussed in [1] and a test is
included to ensure that unstaged changes are still ignored correctly.

When execvp reports EACCES, it can be one of two things:
1. We found a file to execute, but did not have
permissions to do so.
2. We did not have permissions to look in some directory
in the $PATH.
In the former case, we want to consider this a
permissions problem and report it to the user as such (since
getting this for something like "git foo" is likely a
configuration error).
In the latter case, there is a good chance that the
inaccessible directory does not contain anything of
interest. Reporting "permission denied" is confusing to the
user (and prevents our usual "did you mean...?" lookup). It
also prevents git from trying alias lookup, since we do so
only when an external command does not exist (not when it
exists but has an error).
This patch detects EACCES from execvp, checks whether we are
in case (2), and if so converts errno to ENOENT. This
behavior matches that of "bash" (but not of simpler shells
that use execvp more directly, like "dash").

The POSIX standard specifies a return type of int for all six exec
functions. In addition, all exec functions return -1 on error, and
simply do not return on success. However, the current emulation of
the exec functions on mingw are declared with a void return type.
This would cause a problem should any code attempt to call the
exec function in a non-void context. In particular, if an exec
function were used in a conditional it would fail to compile.
In order to improve the fidelity of the emulation, we change the
return type of the mingw_execv[p] functions to int and return -1
on error.
